The driver uses a 32-bit variable to store a pointer, causing a couple of
warnings:

../drivers/staging/bcm/CmHost.c: In function 'StoreCmControlResponseMessage':
../drivers/staging/bcm/CmHost.c:1503:3: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
   (struct bcm_connect_mgr_params *) ntohl(
   ^

   ^
../drivers/staging/bcm/CmHost.c:1564:3: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
   (struct bcm_connect_mgr_params *) ntohl(

I fixed other warnings in an earlier commit 9f1c75ac2dba ("staging/bcm: fix most
build warnings"), but couldn't figure out what was the intended behavior on
64-bit machines here.

The driver was removed in linux-3.19, commit d09e9b160fc1 ("staging: bcm: remove
driver") which explains that it never worked on 64-bit machines. This adds
a Kconfig dependency instead to prevent it from being built in the known
broken configuration. This workaround applies to v2.6.37 or higher.
